An airplane takes off from the runway at an 15 degree angle. A fence is 50 feet away from the location where the plane took off from the runway. What is the altitude of the airplane when it passes over the fence

tan 15 = opposite / adjacent

tan 15 = opp / 50      solve for   opp   the altitude of the plane as it (hopefully) misses the fence....
